we install snapdrive6.2 on the 2 windows nodes.

besides, the vritual name AWOLTPSQLVS is also a Symantec Netbackup client. And the backups run every 15 minutes and it enables "Microsoft Volume Shadow Copy Service(VSS)" to backup the openfile.

we once opened a case about this and the Netapp support thought our issue is relating to Symantec Netbackup as per http://www.symantec.com/business/support/index?page=content&id=TECH87754;

and we indeed have 2 snapshot provides on windows nodes now....since“Data ONTAP VSS Hardware Provider” is installed automatically as part of the Snap Drive software installation.....

so We do the change as per this symantec documentation to edit the registry table to "UseMicrosoftProvider" and reboot the nodes to take it into effect.................

but the error messages is still there.............

is there anybody who have  idea about this? thanks for you patience and thanks in advance!

Re: a snapdrive LUN created and destroyed messages on filer

is this something your team handles or should this be asked in the NetApp Support Community?
